Description

Technical Field

[0001] The utility model relates to the technical field of PVC profile production equipment, in particular to a high-efficiency punching machine for profiles. Background Art

[0002] PVC profiles are industrial and domestic PVC products that are made by adding various functional additives to PVC resin and then extruding at high temperature. PVC profiles with added functional additives are anti-aging, anti-ultraviolet, corrosion-resistant, high-strength, cheap, and have good thermal insulation and heat-insulating properties. They can partially replace aluminum profiles, steel, etc. PVC profiles are widely used in plastic products in the fields of construction, furniture, automobiles, electrical appliances, etc. They have the advantages of light weight, durability, and low cost. The production process of plastic profiles mainly includes three steps: raw material processing, extrusion molding, and subsequent processing. First of all, raw material processing is the first step in the production of PVC profiles. Before production, PVC resin needs to be processed, including adding auxiliary materials such as stabilizers, colorants, and fillers to improve its weather resistance and mechanical properties, and control its softness and hardness. Secondly, extrusion molding is the key step in the production of plastic profiles. Extrusion molding is to use an extruder to heat and melt the treated PVC resin and extrude it through a mold. Finally, subsequent processing is the last step in the production of plastic profiles. During the extrusion process, the plastic profile has been initially formed, but it is only in the shape of a long strip, i.e., a PVC long strip profile. The PVC long strip profile also needs to undergo subsequent processing steps such as cutting and cooling. Some PVC profiles need to be punched during the subsequent processing. Usually, the profiles are cut into predetermined sizes and then punched one by one. The profiles after cutting are small in size and large in number, and the punching operation is cumbersome and inefficient. In response to this, an efficient punching machine for profiles is proposed. Holes are pre-punched in the long strip profile before it is cut, and multiple positions can be punched at one time before cutting, thereby reducing the time consumed in punching and improving production efficiency. Summary of the invention

[0003] The utility model aims to provide a high-efficiency punching machine for profiles, which is provided with a plurality of punching units and can complete the punching of a plurality of PVC profiles at the same time, thereby greatly improving the punching efficiency.

[0017] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings. The described embodiments are only a part of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0018] Reference Figure 1 and Figure 2, this embodiment proposes a high-efficiency punching machine for profiles, including N punching units 1, where N is a natural number greater than 1. The punching units 1 are evenly arranged along a straight line of a guide rail, and the punching unit includes a frame 3, a drilling machine 2, a drilling machine 2 lifting component, an operating table 7, and a fixed component. The drilling machine 2 mainly includes a drilling machine 2 head and a motor. The drilling machine 2 is a prior art, and different models of drilling machines 2 can be selected according to needs, which will not be described here. The drilling machine 2 is movably connected to the frame 3 through the drilling machine 2 lifting component, the operating table 7 is arranged below the drilling machine 2, and the fixed component is arranged on the table top of the operating table 7. The drilling machine 2 lifting component includes a lifting electric cylinder, a lifting guide rail 4, and a lifting moving part 5. The lifting moving part 5 is movably connected to the lifting guide rail 4, and the output end of the lifting electric cylinder is connected to the lifting moving part 5 to drive the lifting moving part 5 to move up and down. The drilling machine 2 is fixedly connected to the lifting moving part 5. When in use, the lifting electric cylinder is started to drive the lifting moving part 5 to move up and down along the lifting guide rail 4, thereby driving the drilling machine 2 to move up and down. The fixing assembly includes a transverse electric cylinder 8 and a transverse moving plate 9, the transverse moving plate 9 is perpendicular to the surface of the operating table 7, and the bottom of the transverse moving plate 9 is separated from the surface of the operating table 7 by a predetermined distance, that is, the bottom of the transverse moving plate 9 is higher than the surface of the operating table 7, and the output end of the transverse electric cylinder 8 is connected to the transverse moving plate 9 to drive the transverse moving plate 9 to move horizontally. By setting the transverse moving plate 9, after placing the PVC long strip profile, the transverse electric cylinder 8 is started to drive the transverse moving plate 9 to move toward the frame 3 until the transverse moving plate 9 abuts against the side wall of the PVC long strip profile, thereby achieving the effect of fixing the PVC long strip profile and preventing the phenomenon of the long strip profile being unstable during drilling, which causes the hole quality to decrease.

[0019] Wherein, N is 20-30. As shown in the embodiment, N is preferably 26. That is, 26 punching units 1 are arranged in sequence along the guide rail, and the intervals between adjacent punching units 1 are equal, so that the punching requirements of 26 PVC profiles can be completed at the same time, and the punching efficiency is significantly improved.

[0020] The punching unit 1 also includes a blowing assembly 6, and the blowing assembly 6 includes a blowing nozzle, a blowing pipe and an air pump, and the blowing pipe is connected to the blowing nozzle, and the blowing pipe is connected to the air pump. After the punching is completed, the air pump is started, and the gas ejected from the blowing nozzle can blow out the debris inside the hole. Preferably, as shown in the embodiment, the blowing nozzle is inclined at a 45-degree angle to the plane of the operating table 7, which is conducive to blowing out the debris in the hole. Furthermore, a detachable collection box can be set under the operating table 7 to collect debris for easy cleaning.

[0021] A pad is provided on the operating table 7, and the bottom of the transverse moving plate 9 is higher than the top surface of the pad. The pad can prevent the PVC profile from being damaged by pressure during the drilling process, and can also protect the drill bit of the drilling machine 2.

[0022] The bottom of the frame 3 is provided with a slider, and the slider is slidably connected to the guide rail.

Both ends of the locking block are provided with threaded holes, and the back of the frame 3 and the side of the guide rail are provided with second threaded holes at positions corresponding to the threaded holes, and the threaded holes and the second threaded holes are fixed by screws. In other words, one end of the locking block is connected to the back of the frame, and the other end is connected to the side of the guide rail, so as to achieve the purpose of fixing the frame on the guide rail. By setting the slider, the spacing distance between the drilling units can be flexibly adjusted, so that it can be used to drill holes of PVC profiles with various size requirements. When adjusting, the screws on the back of the frame 3 and the side of the guide rail are unscrewed, the locking block is removed, and the frame 3 is moved to a suitable distance and then the locking block is fixed with screws, so as to ensure that the position of the frame 3 is fixed.

[0023] It also includes a second guide rail parallel to the guide rail, and the operating table 7 is slidably connected to the second guide rail. That is, the operating table is connected to the second guide rail through a second slider, and also includes a second locking block, and the operating table and the second guide rail are threadedly connected to the second locking block to achieve their relative positions being fixed. When the position of the rack 3 needs to be adjusted, the corresponding position of the operating table 7 also needs to be adjusted to ensure smooth drilling.

[0024] When the high-efficiency punching machine is used for the profile, the operator first pushes the PVC long strip profile onto the operating table 7, starts the transverse electric cylinder 8 to move the transverse moving plate 9 horizontally until it contacts the side wall of the PVC long strip profile; starts the drilling machine 2, the drill bit rotates, and then starts the lifting electric cylinder to move the lifting moving part 5 downward until the drill bit contacts the PVC long strip profile and completes the drilling; after the drilling is completed, the lifting moving part 5 moves upward under the drive of the lifting electric cylinder, and the drilling machine 2 moves upward and starts the air pump, and the blowing nozzle sprays gas to blow out the debris in the hole. The transverse electric cylinder 8 controls the transverse moving plate 9 to move in the opposite direction for a distance to loosen the PVC long strip profile. The operator takes out the punched PVC long strip profile and can complete the drilling of multiple small-sized PVC profiles at the same time.

[0025] The utility model provides a high-efficiency punching machine for profiles. By arranging a plurality of punching units, uncut long PVC profiles are cut into small-sized PVC profiles after the punching is completed. The punching of a plurality of PVC profiles can be completed at the same time, which greatly improves the punching efficiency and saves time.
